Application led September 24, 1904. Serial No. 225,761.

To all whom t may concern:

Be it known that I, FRANK J. MATCHETTE,

y a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Dust-Collectors, of which the following is a specili- Acation, reference being'had to the accomand dirt are taken panying drawing, forming a part thereof.

This invention relates to pneumatic cleaning apparatus in which dust up and removed from carpets, furniture, etc., with a draft or current of air produced by a vacuum or partial connection vacuum.

Its main objects are to lseparate the dust and dirt from the air away-from and independently of the moving suction head by which they are collected'or taken up, thus admitting of the employment .of a light, simple and easily operated device 'for gathering and removing the dust and dirt from -an extended area or fromA different points without carrying the collected dust and dirt about during the operation, and generally to simplify and improve the construction and operation of-apparatus o f this class.

It consists in certain novel features of construction and in the peculiar arrangement and combinations of parts hereinafter particularly described and pointed out in the claim. ,A

In the accompanying drawing like characters designate the same parts inthe several figures.

Figure l is a side elevationv of apparatus embodying the invention; Fig. 2 is a vertical section on the line 2 2, Fig. 3, of the dust separator; and Fig. 3 is a horizontal section of the same on the line 3 3,.Fig. 2.

The apparatus comprises a portable device A, whichV may be called a separator, for

separating dust and dirt from the air withwhich it is taken up and. collected, a portable suction head B, having a iiexible pipe C with `the separator, and an injector D, having a compressed air supply connection VE and constructed and arranged to exhaust air from the suctionhead B and to force it with dust and dirt taken up and carried therewith, into the separator.

The separator A comprises a basin or re ceptacle f for catching and holding dust and dirt as they are separated from the air with which they are collected, a pipe g that class of -leading through one side of said basin and extending upwardly therefrom, a muler h lnto which said pipe opens at its upper end, a bell-shaped deflector i surrounding said muiiier and a straiuerj inclosng said deflector with saidbasin. The basin f is provided with wheels c and a caster Z and with a handle m for movingthe separator from place, to place. The bottom of the basin is provided with a slide n for removing the dust therefrom and the sides of the basin are preferably inclined downwardly and inwardly toward said slide;

The muflier l1, consists of concentric perforated spheres or of inner and outer perforated shells, the pipe q being attached at its upper end to and communicating with thel interior ofthe inner shell, and the outer shell having a depending rim surrounding f by an elastic band s, or other suitable The injector consists of a Y-shaped l casing, the stem of which is coupled to the lower end of the pipe g,'and of a nozzle n threaded in one branch of said casing and projecting into the stem thereof toward its connection with the pipe g. The compressed air pipe pled either with the outer end of the nozzle p or with an elbow connection g, swiveled in one side of the branch of the injector cas. ing in which the nozzle is inserted, the casing being formed inside with an elongated annular recess and the nozzle with a series of lateral ope gs for the passage of air into it from the side connection. The outer end of the nozzle p is squared or otherwise formed to receive a wrench for turning and adjusting it longitudinally in the casing. When the compressed air pipe or hose E is coupled with the elbow connection q, the outer end of the nozzle p is closed with a cap, as shown in Fig. pipe or hose is connected wlth the outer end of the nozzle, the lateral connection wil1 be closed or omitted. The suction hose or pipe l, and in case said E may be cou- C isv connected with the outer branchl of the injector casing, as shown in Fig. 1.

The suction head B is formed in the ,base

or under side with a slot or aperture and is provided with a tubular handle 1, to which the hose or pipe C is attached. This part of the apparatus may be varied in size and form according to the class of work it is designed to perform. The form shown in' Fig. l is specially designed for cleaning carpets, rugs and the like. Suction heads of dierent fqrms and sizes may be provided and used in connection with the same separator for operation on different artlcles and for different classes of, work.

The apparatus -as shown, operates as fol-I lows: The separator A being placed at some convenient point where it will be out of the way, as in the corner ofi a room to be cleaned or 1n an adJoining room, and the) p`1pe or hose E connected with an air comv pressor or source of compressed air, air is admitted to the nozzle p and issuing therefrom in a strong jet, exhausts the air from the suction head B through "its tubular handle and the hose C, and forces it through the pipe g into the separator.. The suction head B is moved by the operator over the surface of the carpet or article tobe cleaned, and the strong air draft induced by the injector through the slot or aperture in the base of said head takes up dust and dirt and discharges them through the pipe g into the muffler z, within and underneath the bellshaped defiector i. The muffler vbreaks up and dissipates the strong air blast issuing from the upper end of the pipe g, preventing or reducing the noise which its unobstructed discharge would otherwise produce. The rim on the under side of the outer shell of the muiler and the defiector i, direct the dust and dirtv downwardly toward the basin f, in which they arecaught and held while lthe air escapes through the strainer y', re-

moving therefrom'fine dust and particles of dirt whichultimately settle into said basin. The nozzle p may be adjusted by screwing it intov or out of the injector casing to secure the most effective operation of the apparatus and obtain the best results under varying `scope of the invention.

I claim: v

In a-pneu1natic apparatus for conveying and separating dust and dirt from'air, the combination of a dust separator comprising a catch basin having an opening in the bottom provided with a closure, a bell-shaped deflector supported above said basin, a strainer open to the atmosphere and enveloping said deflector together with said basin,

a pipe leading into the separator and opening into said def-lector, a 'dust laden air conveying pipe connected with the pipe leading to said deflector, and means ,to exhaustair. from said pipey and force it with entrained .dust and dirt into the deflector in said sepa-v rator, substantially as described.
